Hiya,

Just hit a strange problem, new router, after a week of perfect stability the router started rebooting constantly (newest firmware was in place). I turned off and on / reset to factory settings without success.
So I unplugged all connections and added them back 1 by 1. I found whenever I plugged in one specific computer and accessed the network then the router rebooted.

I use Develo mains adapters but found these weren't at fault.

The same computer works via wireless to the same router and works the same wired connection to a Thomson ADSL router but this same wired connection consistantly causes the draytek to crash.
It's also strange that it's only started occuring and the same setup worked all right for a week with no changes AFAIK. The network card is a DLINK DFE-530TX PCI.
I'll do a scan with AVG Antivirus to see if that finds any infection (but if it was a virus then the wireless connection should have caused same issue?).

Anyone seen something similiar or able to explain this strange behaviour?

Cheers

I had a similar problem but with a VMWare XP virtual machine. as soon at the machine accessed the internet the router would reboot. this happened suddenly after being stable for months. like you i suspected a virus, but nothing detected. I monitored traffic with MS network monitor, nothing unusual. eventually I created a new machine.
you could try a different wired nic and also swap patch cabling and see what happens

Thanks,

I'm planning to go out tomorrow and buy a new NIC as they're cheap enough.

I'm using DLINK DFE-530TX PCI's with a 2820 and they work fine, maybe a hardware fault with that particular NIC.

Thanks, after leaving the offending computer (with the dlink nic) unconnected for a day I reconnected and all was fine.

Great I thought, all fixed. Then I configured my's son pc for print (to a Canon PIXMA4850 connected to the USB port of the router) and the same thing happened. Something occurring on his pc was causing the router to continually re-cycle, when I removed his network cable the router was stable.

All this behaviour seems to co-incide with buying the new printer last Friday.
So my current theory is that's it's unrelated to network cards etc but a problem using the USB port on the router when connected to a printer.
I'll leave the printer unconnected and see if this stabilises everything, if this is the issue then I'll raise with support.

Cheers
